Roundabouts are not just for efficiency, they are for safety. A regular 4-way intersection introduces multiple conflicts between cars turning left and cars coming from the opposite direction.

A roundabout only has one conflict for each connecting street, and the right of way is clearly defined.

They also change the angle of impacts to be less severe since they should effectively eliminate a t-bone type impact.

And collisions will be at a lower speed since no one will be blasting straight through the intersection. Unless someone really fucks up.
